[0002] As box girder quality standards become increasingly stringent, traditional curing processes are struggling to meet these requirements. Traditional curing methods have numerous drawbacks.

[0051] In one or more embodiments, the enclosure 2 includes a baffle and columns connected to the baffle, the baffle is arranged circumferentially along the bottom edge of the box beam 1, and the columns are arranged at intervals along the length direction of the baffle.

[0052] The baffle is made of color steel plate, and the column is square steel. The baffle is supported and reinforced by the square steel. The fence 2 is arranged around the maintenance pedestal 6 and has the same height as the maintenance pedestal 6. The sponge plastic material is used for sealing the contact between the box girder bottom plate and the color steel plate. After the box girder 1 is hoisted to the maintenance pedestal 6, a closed space is formed, that is, the fence 2 and the bottom of the box girder 1 form a maintenance space.

[0053] In one or more embodiments, as shown in Figure 2 The beam end maintenance tooling 3 includes a tooling skeleton 31 arranged at the end of the inner cavity of the box girder 1 and a plastic film 32 covering the tooling skeleton 31.

The inner cavity of the box girder 1 is sealed by the plastic film 32 and the tooling skeleton 31, so that the inner cavity of the box girder 1 forms a sealed space, which facilitates the subsequent humidification device 4 to transport mist to the inner cavity of the box girder 1 to realize the maintenance of the concrete on the surface of the inner cavity of the box girder 1.

[0059] In an optional embodiment, the support skeleton 33 is arranged along the circumferential direction of the tooling skeleton 31.

[0060] Example 2

[0061] On the basis of example 1, as shown in Figure 3As shown, the box girder maintenance device described in this embodiment further includes a maintenance pedestal 6, which is arranged in the annular area and is used to support the bottom of the box girder 1.

[0062] During maintenance, the box beam falls on the maintenance pedestal 6, which supports the bottom of the box beam 1.

[0063] In one or more embodiments, Figure 4 、 Figure 5 As shown, the maintenance platform 6 includes a platform pier 61 and a lifting support 62 arranged on the platform pier 61, and the lifting support 62 is used to adjust the vertical height of the box beam 1.

[0064] Among them, before dropping the beam, the lifting support 62 is first controlled to lift up so that the bottom of the box beam 1 falls on the lifting support 62, and then the lifting support 62 is controlled to drop, thereby driving the box beam 1 to slowly drop until the bottom surface of the box beam 1 contacts the enclosure 2, thereby avoiding the box beam 1 shaking during the lifting process and colliding with the enclosure 2 when the beam is directly dropped, causing damage to the enclosure 2 and the enclosure 2 to be not tightly closed.

[0065] In an optional embodiment, if Figure 6 、 Figure 7 As shown, the lifting support 62 includes a frame 621, a telescopic cylinder 622, a support plate 623 and a lifting plate 624;

[0068] The telescopic oil cylinder 622 is installed in the frame 621, and the frame 621 is connected to the pier 61. The telescopic rod of the telescopic oil cylinder 622 is connected to the lifting plate 624. The up and down displacement of the lifting plate 624 is controlled by controlling the telescopic oil cylinder 622. When the box beam 1 falls, the telescopic oil cylinder 622 is first controlled to lift up, so that the lifting plate 624 rises and is located above the support plate 623. Figure 4 、 Figure 5 As shown, the bottom of the box beam 1 is made to fall on the lifting plate 624, and then the telescopic cylinder 622 is controlled to contract to make the lifting plate 624 descend, thereby driving the box beam 1 to slowly descend until the bottom surface of the box beam 1 contacts the enclosure 2, so as to avoid the box beam 1 shaking during the lifting process and colliding with the enclosure 2 when the beam is directly dropped, causing the enclosure 2 to be damaged and the enclosure 2 to be not tightly closed.

[0069] Furthermore, the support plate 623 is connected to the top of the frame 621, and the lifting plate 624 is movably arranged inside the support plate 623. After the lifting plate 624 is lowered to a height lower than the support plate 623, as shown in FIG. Figure 6 As shown, the box beam 1 falls on the support plate 623. At this time, the support plate 623 supports the box beam 1. Since the support plate 623 is connected to the top of the frame 621, the gravity of the box beam 1 is transferred to the pier 61 through the frame 621, avoiding the long-term stress on the telescopic cylinder 622 and providing stable support for the box beam 1.

[0070] In the present application, the top surface height of the support plate 623 is consistent with the height of the enclosure 2, ensuring that after the top surface of the box beam 1 falls on the support plate 623, the bottom surface of the box beam 1 is in contact with the enclosure 2 at the same time.

[0072] Furthermore, the pier 61 is provided with reserved bolts, the bottom plate 6211 is connected to the reserved bolts, the top plate 6212 is provided with a cavity in the middle, the telescopic rod of the telescopic cylinder 622 extends from the cavity and is connected to the lifting plate 624;

[0073] Furthermore, bolt holes are formed on the top plate 6212, and the support plate 623 is connected to the top surface of the top plate 6212 by screws;

[0074] Furthermore, if Figure 8-Figure 9 As shown, the telescopic oil cylinder 622 is further comprised of a locking member 625, which is divided into a first locking plate 6251 and a second locking plate 6252. The telescopic oil cylinder 622 is located between the first locking plate 6251 and the second locking plate 6252. Both ends of the first locking plate 6251 and the second locking plate 6252 abut against the vertical rod 6213. The first locking plate 6251 and the second locking plate 6252 are connected together by bolts. The telescopic oil cylinder 622 is clamped by the first locking plate 6251 and the second locking plate 6252 and fixed to the vertical rod 6213.

[0075] Furthermore, it also includes an L-plate 626, and a pad 6214 is installed on the outside of the vertical rod 6213. One side of the L-plate 626 is fixed to the pad 6214, and the other side of the L-plate 626 is fixed to the support plate 623. The support plate 623 is reinforced by the L-plate 626.
